In the recent hot Disney cartoon "Super Marines", the medical robot "Big White" like cotton candy has sprouted the hearts of many fans. It will automatically activate, scan the body signs, provide medical reminders when you hear screams, and take care of yourself when your host is in a bad mood... There is a private health consultant who is both cute and warm, away from us. How far is the real life? Recently, the reporter interviewed the robot research experts of Southeast University and analyzed the scientific and technological content of Dabai from the perspective of technology house. Experts say that it is expected that in about 5 years, a warm-hearted "health advisor" who can do care, such as Dabai, can be hugged with people and comforted by language can be created.

Is there a medical robot like Dabai?

Robotic rehabilitation trainer has been "on the job"

"Hello, my name is Dabai, it is your personal health assistant. When you scream, I will notice that you need medical care." This is the scene in the "Super Marines".

"The white that looks like a polar bear! It’s too hot in the circle of friends recently." On March 9th, the reporter just mentioned robot white, dean of the School of Instrument Science and Engineering, director of the Institute of Robot Sensing and Control Technology. Song Aiguo bluntly read the photos of Dabai, and he grew too cute.

The problem is that carbon fiber bones, balloon jackets, voice recognition and human body sign scanning capabilities, together with the three major technologies of robot manufacturing, mobile medical and artificial intelligence, how far away from our real life?

"Many sci-fi films are based on scientific research. What we are doing now is to work hard in this direction." Professor Song Aiguo told reporters that medical robots are widely used, such as robots for various organ operations, and medical research at Dongda University. The robot focuses on rehabilitation and helps patients recover their functions by assisting with training.

Song Aiguo introduced that China is in an aging society with more stroke patients, but there are too few rehabilitation trainers. Using robots instead of rehabilitation trainer-assisted training can reduce the labor intensity of doctors. "Now research on medical robots is intelligent, and medical records can be recorded in real time, and judgments can be made according to the situation. For example, patients wear wearable sensors. If patients are too active in training, As the blood pressure rises, the robot will judge that the training is not suitable or the training intensity is reduced."

Moreover, after the introduction of Internet of Things technology, patients can be trained at home or in community hospitals. Doctors can remotely monitor 3-5 robots through the network. The robot transmits the patient's physiological information to the doctor, and the doctor can talk to the patient in real time. “Now, this kind of self-service and recreational rehabilitation robot based on the Internet of Things has been demonstrated in Beijing and Shanghai. It is expected to be demonstrated in some hospitals in Nanjing this year, such as Zhongda Hospital.”

Can you be as careful and warm as Dabai?

Dongda is studying robots with "emotional intelligence"

I am used to being a cold-blooded robot with an electronic texture. I can always feel the change of my master's emotions and see through the thoughts. Song Aiguo revealed that Dongda is also studying this kind of robot with emotional intelligence. “In order to change the appearance of the robot's cold ice, we designed the rehabilitation robot like a game console. We will add voice interaction and tactile sensors in the future. For example, if you pat it, it will respond. Also let the robot have 'emotional intelligence'.” Song Aiguo Introduction, the related technology of Dongda Robot is mainly to identify the face information through the camera. For example, according to the change of mouth shape and eye shape, the mouth angle is pulled down when sad, and the eyes are bent when laughing. "The camera mainly performs image processing, feature extraction, and target recognition, but the emotions recognized are only a few major categories, such as the same laugh, happy smile, sneer, some facial laughter but inner sorrow, and the expression of the person is disguised. Sex, this makes it difficult for robot recognition. In addition, Dongda also has a teacher who specializes in robot speech recognition, which is identified by changes in emotional sounds when people are sad, tired, and happy. "The other way is to identify people's physiological information, such as pulse, heart beat changes. Like the white, so science fiction is based." Song Aiguo explained that there is a parasympathetic nerve in the pulse, this nerve The signal is affected by human emotions. "We are also able to extract emotional signals in the pulse. It is very difficult in this respect. The emotional signal is a weak signal and is interfered by many signals, just like in dozens of people. I heard the voice of the man at the end of the team."

Not only that, but also the signals corresponding to different emotions, what signals are happy, what signals are nervous, etc. "There is no fixed template for this division, which involves psychology. Just like a polygraph can lie, But people with strong psychological qualities can also fool the lie detector."

Vitamin

Another benefit of vitamins for the human body is that it can help the growth and development of the human body to operate normally, especially for teenagers, vitamins are one of the essential nutrients in the growth process. For example, vitamin D can well adjust the metabolism of some trace elements in the human body, and can also promote the absorption of calcium by the human body, maintain bone health, and maintain a balance between the blood phosphorus level and the blood calcium level in the human body.
